[RESOLVED] Error handling question... Where did it come from?

[tassa]

Hello,

I'm wondering if there is any way to know where did the error come from. I have this:

Try
                Select Case MathOperation
                    Case Divide
                        'Divide a/b
                    Case Multiply
                        'Multiply a*b
                    Case Tangent
                        'Calculate tangent
                End Select
            Catch ex As Exception
                Return "Error"
            End Try

When I say "where did the error come from, is which case threw the error.I know I could check the values and throw an exception, but I want to know which case produced the exception.

I hope it's clear .

Thanks in advance!

PS: That's just an example.
